Web4 feb. 2024 · Barium has an atomic number of 56, which means that it has 56 protons in its nucleus. The number of protons in an element’s nucleus determines how many valence electrons it has. Barium’s valence electron configuration is 2s2 2p6 3s2 3p6 4s2, which means that it has two valence electrons in its outermost energy level. WebThe total number of neutrons and protons (symbol A ), or mass number, of the nucleus gives approximately the mass measured on the so-called atomic-mass-unit (amu) scale. The numerical difference between the actual measured mass of an isotope and A is called either the mass excess or the mass defect (symbol Δ; see table).
